The latest NBA Power Rankings are out on SI.com and two teams that stand out are the Los Angeles Lakers and the Miami Heat, which are ranked third and fourth respectively. SI’s Robin Lundberg says the Lakers have a strong case to be number one after winning five straight games. He also adds that the Heat’s strong rookie guard tandem of Tyler Herro and Kendrick Nunn boost a versatile squad led by Jimmy Butler that could be a sleeper in the East.
